10 Weeks Flowering - Yellowing Leaves - This Normal? - Pics

very nice lst and the budzzz look chronic

John Michaels said:

Plants are 10 weeks into flowering. He is currently running roughly 170 true watts with temps around 76 to 83 F. He has read a lot that this is normal and could be an indication that the plant is reaching maturity.

When was the last time you fed this plant?

It looks great Mate.
Is that done under cfl?

Its a plant/light thing. If the trics are ambered up pretty good i'd say chop. If you grow a plant that wants to stretch, with cfl's, it will grow tall and make using cfl light efficiently a difficult proposition. If the trics are ambered, you reach a point of diminishing returns, if your waiting for it to fatten up. Mature plants yellow up and the fan leaves get shitty near the end of life.

looking really nice the yellowing normal i think coming to end of flower nice lst

Yellow leaves do not indicate maturity, it happens because you let the levels of nitrogen available in the soil go low enough so the plant starts taking the next available source of nitrogen and that is the fan leaves. People let the nitrogen go low near the end of flowering and hence the yellow leaves, had you had too much nitrogen in the soil you wouldn't have yellow leaves but dark green ones.

Peak maturity to me is when most of the hairs turn red and wither and receed back into the calyx which is very swollen. Your buds don't look like they are ready to harvest, i would assume you probably have three weeks left. You might add one last small dose of nitrogen with your next dose of bloom ferts just to see it through to harvest. You probably only got a few waterings left before harvest if your soil dries in a week or under so plan the last feeds/waterings and flush.

Those buds look awsome and if finished properly are gona be sh!t hot smoke. Nice looking plant too.

You say week 10 of flowering but i call the start of flowering 'when flowers first apper' and not when the lights are first put on 12/12???

Its a great cfl grow.
I am trying a red spectrum 250w for flowering at the moment.
Its my first time without hid so thanks for the confidence boost!
